HARROW ATTACHM ENT.

SPECIFICATION forming part of Letters Patent No. 493,310, dated March14, 1893.

Application filed July 26, 1892- Serial No. 441,286. (No model.)

To all whom it may concern.-

Be it known that I, JOSHUA RAYMAN SToRrE, a citizen of the UnitedStates, residing at Travisville, in the county of Pickett and State ofTennessee, have invented a new and useful Harrow Attachment, of whichthe following is a specification.

My invention relates to barrows, and more particularly to a new andimproved harrow attachment designed to regulate and facilitate the useof the harrow on uplands and inclinations.

My improvement comprises a self-adjusting gravitating Weight, arrangedto swing in a prescribed arc of a circle on top of the harrow-frame, andsupported by a rod oscillating from a fixed center at some suitablepoint on top of the harrow-frame, whereby the necessary weight forembedding the teeth of the harrow in the soil is directed and adjustedto theproper point according to the gravity.

My invention consists further in certain details of construction,arrangement and combination of parts, all of which will be more fullydescribed hereinafter, and the specific points of novelty in which willbe particularly designated in the appended claims.

Referring to the accompanying drawings: Figure 1 isa perspective viewshowing my improvement attached to an ordinary harrow. Fig. 2 is a topplan View. Fig. 3 is a detail View of the swinging Weight and itssupporting and adjusting means.

Like letters of reference indicate like or corresponding parts in theseveral views of the drawings.

A indicates a harrow of any ordinary or approved construction, provided,as usual, with the barrow-teeth a a and the clevis B. In this particularinstance the harrow is shown as made in two sections, 0 C, suitablyhinged together, and to a certain extent independent in operation. beingfor the usual purpose of permitting either section to be uplifted tofree the teeth from any clinging foreign matter, without disturbing theposition of the other section.

D D D respectively designate the longitudinal supporting beams, which,together with the transverse braces E E, constitute the At a suitablepoint on top of the harrow, such as near the forward extrem- The objectof this construction ity of the beam D, I locate an angle-iron F,consisting of the vertical portion 1) and the horizontal rectangularprojecting arm 0, having a central circular orifice (I, located thereinto receive and permit the oscillation of the swinging arm G, having atits forward end the downwardly-extending finger 6, provided with alimiting shoulderf, and screw-threaded at its extremity to receive andhold the correspondingly screw thread ed retainingnut H, which preventsthe removal of the arm G from its pivotal support, while the limitingshoulderf prevents the finger e from descending too far in the orificeof the support. On the rear extremity of this arm G is loosely mountedthe cylindrically shaped roll or weight I, made of some cheap heavymetal, and longitudinally and centrally perforated, whereby it islooselyand rotatably mounted on the arm G, being limited fromlongitudinal displacement thereon in either direction,

forward or backward, by the stop-nuts g g, running on screw-threadsformed on the exterior of the rod or arm G. The said weight I isdesigned to swing in an arc of a circle on suitable guide-ways orsupports over both sections of the harrow, the center of the are beingthe angle-iron E, as clearly shown in Fig. 1. To this end, J designatesa curved guiderod or bracket placed in a higher horizontal plane thanthe top of the harrow and held in such position by means of its bentdownwardlyprojecting extremities, respectively bolted to the beams D Dsaid guides being bent to conform to the curvature of the arc of thecircle in which the weight I is designed to swing; and the curvature andcontinuity of this are is preserved, on the other section of the harrowby a similar guide J of like construction, and secured in the samemanner as the guide J to the respective beams of the other section. Thebreak or space between the adjacent ends of the guides J J is spanned bya yoke-rod K, having at each extremity an eye h, loosely embracing aguide J or J, as the case may be, and its body-portion preserving thealignment and shape of the continuous guideway, thus forming a bridgebetween the two sections and preserw ing the continuity of thearc-shaped guideway, extending unbrokenly over both sections of theharrow. By means of the loosely-embracing eyes h, the yoke K ispermitted to move in a corresponding manner to the hinges when it isnecessary or desirable to uplift one of the barrow-sections.Respectively at each extremity of the guideway is located anupwardly-pro j ecting guard or stop L, for the obvious purpose ofpreventing the weightI from rolling off at either end of said guideway.

It will be noticed by inspection of Fig. 1 that from each extremity theguideway slopes downwardly or converges toward the center thereof, whichcenter is intermediate of the two harrow-sections. Thus it will be seenthat the normal tendency of the gravitating weight I, on level ground,is to occupy the position shown in Fig. 1; but, on the other hand, itwill be understood that when either section occupies a higher plane thanthe other,as would occur where the same was being used on a hillside,--the Weight I will roll along the guideway under the influence ofgravity, descending to a set position hearing upon the lowermostsection, and serving to embed the teeth of the same firmly in the soil.

Having thus described my invention, what I claim is 1. In a harrow, thecombination with the frame thereof, of an oscillating arm pivotallysupported thereon and provided at its rear extremity with a gravitatin gweight arranged to shift in the arc of a circle and bear upon the saidframe in accordance with the influence of gravity, substantially asdescribed.

2. In a rectangular harrow, the combination with a harrow-frame and asuperimposed track formed on the arc of a circle and extendingdiagonally across the frame, said track declining from opposite endstoward its center, of a movable superposed weight arranged to shift itsposition in accordance with the influence of gravity, substantially asdescribed.

3. In a harrow, the combination with a harrow-frame, of an oscillatingarm fixed on said frame and arranged to swing in the arc of a circle,the gravitating weight carried at the free end of said arm and rotatablymounted thereon, and suitable supports or guides for said weightarranged in an arc of a circle on top of the barrow-frame, substantiallyas described.

4. In a harrow, the combination with a harrow-fra-me, of an oscillatingarm fixed on said frame and arranged to swing in the arc of a circle,the adjustable gravitating weight carried at the free end of said armand rotatably mounted thereon, and suitable supports or guides for saidweight arranged in an arc of a circle on top of the barrow-framesubstantially as described.

5. In a harrow, the combination with a harrow-frame, of an oscillatoryarm pivotally supported above said frame and arranged to swing in thearc of a circle, the adjustable gravitating weight carried at the freeend of said arm and rotatably mounted thereon, and a suit-' able supportor guideway for said weight also arranged in an arc of a circle abovethe top of the barrow-frame, and sloping or converging from bothextremities to its center in a downward direction, as set forth.

6. In a harrow, the combination with a harrow-frame, of an oscillatoryarm fixed on said frame and arranged to swing in the arc of a circle, anadjustable gravitating weight carried at the free end of said arm androtatably mounted thereon, an arc-shaped guideway or support for saidweight permitting its free rotation thereupon, and limiting agenciesrespectively at the ends of said guide-way, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
